261 129 613 Added air intake flapper. New engine tin piece with hole to accept Preheat tube which comes up from the left side of the engine tin and goes into the bottom of the air cleaner. Also changed straps so that they hooked up higher. Webmaster note: I have one of these, same P/N....its identical, but the weird part is that it *doesn't* have a nozzle for the crankcase ventilation like the ones in the pictures. May have had parts miss matched at one time....... |

| Bracket for air cleaner, attaches to the outer coil bolt and helps support the arm of the cleaner. Used for 60 and earlier cleaners until the cleaners started coming with a welded on bracket that attached to the truck body for support. This bracket attached to the cleaner arm, and to the coil bolts. |  Anyone know the year difference between the bracket with the notch, and the one without? |
